Solution:
Your problem `->` The mean of observation is 10 . If we add 2 and then multiply or divide by 3 in each observation, then find the new mean ?


Here Mean X `= 10`

Now if we add `2` and then multiply by `3` in each observation, then mean gets increased by `2` and then multiplied by `3`.

`:.` new mean `= (10 + 2) × 3 = 36`.
